I did Atkin for 2 weeks. Atkin is counting carbs, not calories. So I just eat when I am hungry, but I also log it in fit day. Turn out, I actually eat less calories when I did Atkin. 1200cals average. when I just counting calories, 1200 is too little, I am too hungry. I think high protein diet make you feel fuller longer or something. But after 2 weeks I felt cramp, so I stop. I do atkin to just break my plateau. I will try again this week, bc seem like I am stall again.
